Hi, Pengo.

If I'm reading your Lay bets correctly, then your calculations may not be accurate and if so, it is doing an injustice to your results.

For example, today at Pt Lincoln race 5 - your post says you are staking $10 at a Lay price of $10.50 on Grand Palais and that the liability is $105. In your calcs your stake of $10 has not been deducted and therefore the true liability is only $95.

If you go to Betfair and input a stake of $10 on a Lay price of $10.50 you will see that the liability is $95.

Miami Rose at Sun Coast race 4 is unfortunately an accident. Most layers have a cut-off price and will not Lay over that certain price. As it paid double-figures on Unitab maybe its Betfair price would have eliminated it from being a selection?

Good luck.
